As the name implies, these frogs are typically found in trees or other high-growing vegetation. They do not normally descend to the ground, except to mate and spawn, though some build foam nests on leaves and rarely leave the trees at all as adults.

Many tree frogs can change their color for better camouflage. For instance, the grey tree frog (Hyla versicolor) can change its color from green to grey to yellow .[2]
